Checks

The number plate light receives pwm power supply from the dashboard. If necessary, power the number plate light with a 12 v external power supply to test function (connect correctly as indicated in the wiring diagram).

Check congruence of the ground connection on the number plate light.

Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to vdc, open circuits).

If none of the aforementioned tests identifies the problem, replace the dashboard.

Note

Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.

Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
